Eraze or wipe hard drive on HP laserJet 1320

Guys,

We are trading in some of our printers and I'm looking to wipe anything stored on HP LaserJet 1320
HP states that upon returning or trading in a printer they will wipe the hard drive or crush it.
Just wondering what would be the best way of going about erasing the data yourself. I just don't feel comfortable sending thi sthing in and hoping that somebody will eventually erase it.
Please provide step by step instructions if possible..., I wasn't able to find any info on how to erase the data other then just trashing the printer and the drive.

I think maybe the warning you are looking at for HP returns / trades is a generic warning that applies to everything returned to HP - including laptops or desktops which DO contain hard drives.

I don't think there is anything special that needs to be done on the printer to "wipe" any sensitive information off of it. If it were a network printer or something more sophisticated I might say reset the network settings back to factory defaults, but that doesn't apply to this printer either.

That`s what I thought also, but then HP also lists secure erase and they explicitly listed laserjet 1320
So, I thought, perhaps there is something in it. Go figure... I will just do a hard reset on it.
